1 Claim. This invention relates to a method of and a pressure means forproducing in cream a con-' dition substantially the same as that knownas whipped cream."

The invention is adapted to convert the ordinary cream from cow's milkinto a whipped condition either forhousehold use or for any otherpurpose, and in any situation where it isfound necessary 'or desirableto treat the cream. in such a manner as to render it'the equivalent ofwhipped cream.

Although the invention provides a means for converting cream into acondition wherein its' rendering them moreeasily digested by the humanstomach.

A further object of the invention is to provide a superior means foraerating the cream simultaneously with reducing the size of its fatglobules, as aforesaid.

More specifically speaking, the invention pertains, in part, to animproved stopper operated outlet control structure for fluids bottledunder pressure.

Other objects, advantages andfeatures of the invention may hereinafterappear.

Referring to the accompanying drawing, which illustrates what is atpresent deemed to be a preferred embodiment of the invention,

Fig. 1 is'a view showing the ,device. embodied in an upstandingfluid-tight container, some parts being shown in vertical mid-section,and

other parts in side elevation.

Fig. 2 is a cross section on line 2-2 of Fig. 1.

Fig. 3 is a cross section on line 3-3 of Fig. 1.

Fig. 4 is a section on line 4-4 of Fig. 1, being a reproduction of theupper portion of FigJl except that the spout has been removed andreplaced by thecharging tube. v

Referring in detail to the drawing, the main or lower tubular containersection or cup 10, de-

sirably made of sheet metal, is shown having an upwardly directedmouthsurrounded'by an unthreaded annular portion ll below which'threadsI2 are formed in the sheet metal wall thereof.

On to saidcup I0 screws the threaded skirt portion l3 of the dome orupper container section ,said skirt portion I! having threads Ii pressed1938, Serial No. 223,23 (01.225-22) into the sheet metal thereof tocooperate with the aforementioned threads l2.

A packing ring I9, which is outwardly convexedand inwardly concaved asseen in cross section, is provided to make a fluid tight fit between thecontainer sections .l0 and I4. Said ring is held in place by an internalannular seat l8 formed in .the upper container section l4.

In the assembled structure the member l4 may be defined as an invertedupper cup which is connected in a fluid tight manner with the lower cup10. In the top of said member M is' .a circular central opening it whichis normally closed in a fluid tight manner by a stopper structure ll.

Said stopper structure ll includes the circular stopper cup .29 thebottom portion of which is fitted snugly into said opening iii and theninternally .peened over at 2| to insure a fluid tight fit. Said cup 29,in turn, has through its bottom a circular central tapered opening 22,which opening is surrounded by a downwardly directed annular lip 23formed in the bottom of the cup.

Owing to the fact that the bottom section ll] of the container isdetachable from its upper section I, access is afforded to the interiorside the peen 2| at the bottom of the cup shaped closure 29. a

A valve structure is provided to control the flow of fluid through saidopening 22, this valve structure including a valve head 25 furnishedconcentrically with a stem 26. Said head 25 has in its upper face anannular groove 21 within which is fitted a gasket 28 with which the lip23 normally contacts to make a liquid tight fit,

The valve stem 26 is externally screw threaded to have screwed on to ita nut 29, and a compression spring 30 acts between said nut and thebottom of the cup 20 normally to keep the opening or part 22 closed. Thelower portion of the stem '26 is cut away or peripherally flattened at3| at a plurality of points (see Fig. 3) in order to provide dischargepassages for. the bottled liquid when the valve is depressed against theopposition of the spring 99, and the nut 29 is also 2) to permit theliquid to pass upwardly out of the mouth of the stopper cup 20. Theopposite end portions 29a of said nut have a working fit within thecircular wallv of said cup 20. In order to depress the valve structurememof the opening in the latter section to produce.

flattened. externally as indicated at 32 (see Fig.

bers 25,16 and 29 agalnst the opposition of the spring 30 the spoutportion '35 of the cap is furnished with a central internal sleeve thelower end of which is abuttable against the nut 29.

\ Said spout portion 35 has a skirt 31 which has i her 35 down and causeits internalv sleeve 36 to depress the nut 29 and open the port 22.

Owing to its downwardly tapering form the annular passage 22 causes afunnel-shaped expansion of the stream discharged therethrough,

which aids in securing the desired whipped condition. The taper of saidpassage also makes it easier to cleanse it. i

The downward movement of said nut is limited by the annular shoulder 29sprojecting internally from the cup 20.

The sleeve 36 has lateral openings 39 to admit outfiowing liquid. Theupper portion of said sleeve is tightly fitted within the outlet passage49 which in turn has a'slitted nozzle portion ll.

i4. Said puncturing means consists of apin 59 the end portion 5i ofwhich is externally screw threaded to screw into an internally threadedsocket provided therefor in the valve stein 2E. The puncturing end ofsaid pin is beveled as shown at 52 and a groove 53 extends'from end toend of the pin along the side thereof where said bevel is lowest, saidgroove forming a channel for the compressed gas to pass through duringthe charging operation,

The charging tube 45 has within it an inner container 54 the loweroutlet end of which is normally closed by the aforesaid soft metal body46. Said tube 45 also has an internally screw threaded skirt portion 55of the same diameter as the skirt 31 of the removable spout-member 35,thus adapting the charging tube for being screwed on to the container inplace of said spout member The soft metal body 46 is contained within atapered neck 4! with which the container 54 is provided and is therebyheld in a 3 position to be punctured by the member 59. The

charging tube 45 is furnished with a vent 48 to release air pressurecaused by screwing said tube on to the container. Said tube is alsofurnished, during the charging operation, with a packing collar 49having an external annular shoulder 49s around itsupper end to abutagainst the upper end-of the cup member 29. Internally said collar 49has a fluid tight fit around the lower end portion of applied container54.

Referring to certain details of construction,

the packing ring I9 is furnished along its lower edge with a somewhatinwardly directed edge portion or lip I9a externally around which ex:-tends the upper edge portion ll of the lower container section when thetwo sections of the containei are screwed together. Said packing ringalso has a like upper lip l9b. Owing to this construction said packingring, which should be made of a. good grade of flexible rubber, fornlsan effective seal for the compressed liquid, when the liquid levelstands thereabove, or for the gas when the liquid level falls below it.

Before the two container sections are screwed together the lower sectionIII is filled with the body of liquid 55 and is maintained in anupstanding position while the upper section, carrying the packing. ringI9, is screwed thereonto.

In theoperation or charging the container the charging tube 45 isscrewed down upon the part I! sumciently to cause the pin 59 to puncturethe soft metal body 46 and thus provide an outlet passage therefromleading through the groove 53 of the pin 59 into the interior of thestopper structure ll. Screwing downthe charging tube to the extent juststated will cause the lower end of the neck 41 of the charging. tube todepress the nut 39, carried by the valve stem 26, and

container a short distance its soft metal closure body 45 will come intocontact with the point of the pin 59, but the spring 39 will not ofi'erenough opposition to cause theonscrewing of said tube to puncture'saidbody. However further downscrewing of said tube will bring the innerface of the nut 29 into contact with the annular shoulder 2s thuscausing a positive obstruction to the further yielding of the puncturingmember, which will then perform its puncturing operation and cause thecompressed gas to enter the con-- tainer. After the container has thusbeen charged the charging tube is unscrewed therefrom, the

valve head 25 resuming its seat as soon as the charging tube has recededsufliciently to allow 7 it to do so. Thereupon the spout member 35 isscrewed into place to the extent shown in Fig. 1 and the container isready to be used as a means for dispensing the liquid contained therein.

In dispensing the liquid the operator, while holding the container in aninverted position over a receptacle into which the liquid is to bedischarged, will screw the spout 35 farther on to the neck of thecontainer, thereby causing the internal sleeve 36 of said spout forciblyto engage the nut 39 of the valve structure and open the a by saidvalve, said valve having a stem extending axially within said neck, aguide plate carried by said stem and having peripheral portionsinteriorly engaging said neck with a working fit, said plate havingcut-away portions afiording outlet passages for fluid, a dispensing caphaving an upper nozzle portion and a skirt portion to screw on to saidneck, said cap having an axial discharge passage which leads from thespace circumscribed by its skirt to itsnozzle portion, an axial internalsleeve having its upper end portion secured within the lower portion ofthe last recited passage and its lower end abuttable against said guideplate to open the valve when the aforesaidcap is secured down, saidsleeve having openings to admit the fluid to its interior after it hasflowed through the aforesaid cut-away portions of' said guide plate, anda spring positioned to act upon the lower side of said guide plate toclose saidvalve when said cap is screwed back to its original position.
